....reaching running temp the idle varies between 1400~1500 RPM. That's backwards from what it should be? I have replaced several hoses, checked all areas I could with spritzes of carb cleaner without any effect, so what other components regulate RPM at temperature? I'm no mechanic with the finer details of the D-jet system on my 1.7L motor.

The AAR (auxiliary air regulator) is probably stuck in the open position. Needs to be cleaned by soaking in carb cleaner or replaced if the heating element has gone bad and no longer closes the valve.

Now I'll just have to discover where the AAR is located and what it looks like! (IMG:style_emoticons/default/confused24.gif) |
